TABLE FOR HOOPING COILED VIETAL.

SPECIFICATION forming part of Letters Iatent No. 643,472,dated February13, 1900.

Application filed December 6,1899. Serial BT03391378. (No model.)

To LLZZ whom t may concern:

Be it known that I, WILLIAM A. COWLES, a citizen of the UnitedStates,residing at Ansonia, county of New Haven, State of Connecticut,have invented a new and useful Table for Hooping Coiled Metal, of whichthe following is a speciiication.

My invention has relation to the preparation of coiled sheet metal forhandling and for shipment.

In producing sheet metal in rollingmills the metal as it comes from therolls is coiled upon a mandrel, and it is necessary quite frequently tore-coil the strips of metal after the various operations that may have'been performed upon them. After each ceiling operation the strip ofmetal is removed from the mandrel upon which it has been coiled, and thestrips are prevented from uncoiling by means of hoops or bands,which areslipped over them while they are held tightly. My present invention hasnothing to do with the coiling of the metal, but relates only to thehooping of the coils after they are removed from the mandrel. Thisoperation as it has heretofore been performed in brass-mills has eitherrequired the services -of two men or else has necessitated the stoppageof the rolls while a coil was being hooped, as it is impossible for oneman to hold and hoop a coil of metal and at the same time to startanother coil on the mandrel.

YVith the above conditions in view my in# vention has for its object toprovide a table and holding device upon which each coil of metal may beplaced when removed from the mandrel and by which it will be held fromuncoiling while the operator starts a second coil on the mandrel, theoperator having ample time to hoop each coil whileV the next coil isrunning through the rolls, thereby effecting an important saving in thecost of production.

` In the accompanying drawings,fo1ming part of this specification,Figure 1 is a front elevation of my novel hoopingtable complete;

Fig. 2, a plan view thereof; Fig. 3, an end elevation as seen from theleft in Fig. 2, one of the leg-sockets being in section; and Fig. t is asection on the line 4 4 in Figs. 1 and 2.

'other one.

10 denotes the bed or table proper, and 11 It will of course be obviousthat my novel table must be fitted to sustain heavyweights and towithstand rough usage, while at the same time unnecessary Weight is tobe avoided. In practice I have made the table proper of brass and thelegs of iron, although of course it is wholly immaterial so far as theprinciple of my invention is concerned of what special metals the partsare made. The legs are shown as provided at their upper ends With anges12, which fit closely in sockets 13, said sockets being bolted to theunderside of the table.

In use the operator places each coil as he takes it from the rolls orafter a scouring or polishing operation and places it upon the table,Where the coil is retained by a holdingplate 14, preferably curved, asshown, in connection with holding-pins 15.

16 (see dotted lines, Figs. 1 and 2) denotes hoops ready tobe placedupon the coils, which are shown as hanging from a suit-able holder 17.The holding-plate, which should be narrower than the coiled strips ofmetal that are to be hooped, may be conveniently adj usted vertically orremoved and replaced by an'- I have shown this holding-plate asadjustable on a retaining-plate 18, which is bolted to the table and isprovided with vertical slots 19 and a vertical recess 20,which receivesa corresponding projection 2l upon the holding-plate.

22 denotes a guide-pin rigidly secured to the table and passing throughthe holdingplate,and 23 denotes bolts which pass through the verticalslots and engage the holdingplate, the heads of theboltslyingon the backof the retaining-plate and acting by engagea ment therewith to lock theholding-plate at any required vertical position relative to theretaining-plate that may be most convenient in connection with anyspecial width of coils of metal that may require to be handled upon thetable. It will be apparent that the guidepin and the engagement ofprojection 21 onthe holding-plate with the vertical recess in theretaining-,plate will keep the holding-plate steady at any adjustment atwhich it may be placed. The holding-pins are carried by a cross-head 24and extend upward through guides 25 and through the table, their upperends lying flush with the surface of the table when at the loweredposition, as in Fig. 3, and extending some distance above the table whenat the raised position, as in Fig. 4. Guides 25 are shown as madeintegral with a web 26, ears 27, and a plate 28, which is bolted to thebed. The cross-head and holding-pins are carried by a rod 29, which isadapted to slide vertically in a guide 30, carried by a cross-piece 3l,which is bolted to the front legs. The upper end of rod 29 is shown asthreaded and as passing through the cross-head, nuts on the threaded endon opposite sides of the crosshead locking the parts rigidly together. Aspring 32, which bears upon guide 30 and upon the cross-head, acts toretain the latter and with it the holding-pins at the raised position.At the lower end of rod 29 is a footpiece 33, by which the rod,cross-head, and holding-pins may be drawn downward against the power ofthe spring.

34 denotes a locking-lever which in form is a bell-crank lever and ispivoted between ears 27 under the table. One arm of this locking-leveris provided with a locking-lug 35, which is adapted to engage thecross-head to retain the latter and the holding-pins at the loweredposition, as in Fig. 3, and the other arm is provided with a handpiece36 for convenience in manipulating it in use.

37 denotes a spring one end of which is secured to one arm of thelocking-lever, the free end bearing against the under side of the tableand acting to retain the locking-lever in such position that lug 35 willengage the cross-head when the latter is moved down and will retain thelug in the engaged position until the cross-head is released by pressingdown upon handpiece 3G.

I have shown the table as provided with a holder 17 for hoops, so thatthey will be convenient for use. This holder is simply a rod adapted tooscillate and to slide in bearings 39, bolted to the underside of thetable. The outer end of the holder is upturned, as at 40, to enable itto retain a quantity of hoops in place, and the holder is retained atits operative position, as in full lines in Figs. l and 2, or at itsinoperative position (see dotted lines, Fig. 2) by means of lugs 41 and42 upon the rod. These lugs are shown as cast in a single piece, whichis secured to the rod by a pin 43. (See Fig. 4.)

44 and 45 denote spring locking plates which are secured to bearings 39and are adapted to be engaged, respectively, by lugs 41 and 42. Vhen theholder is in its operative position, lug 4l will be engaged by springlocking-plate 44, and the holder will be retained in place thereby.Should it be desired for any purpose to move the holder out of the way,it may be given a quarter-turn and pushed inward under the table, asindicated by dotted lines in Fig. 2, and may be locked in this (itsinoperative) position by the engagement of lug 42 on the holder withspring locking-plate 45 under the table.

The operation,which it is thought will be clearly understood, is briefiyas follows: The

operator places the coil of metal that is to be hooped upon the table,pressing it against the holdin g-plate and releasing the cross-head bymeans of handpiece 3G, allowing spring 32 to raise the cross-head andholding-pins, the latter passing on the outer side of the coil of metalopposite to the holding-plate and retaining it against uncoiling. Thehoops are made just large enough to go easily over the coils of metal.The instant a hoop is in place the operator presses down upon thefootpiece and withdraws the holding-pins, when the coil of metal willinstantly expand and fill the hoop tightly. The operator may of courseretain the holding-pins at less than their normal height by keeping hisfoot upon the footpiece. The instant the cross-head has reached itslowered position it is locked there by the engagement of lug 35therewith, thus leaving the entire front of the table clear for theremoval of the hooped coil of metal and for the placing thereon ofanother coil of metal to be hooped.

Having thus described my invention, I claiml. In a device of thecharacter described the combination with a table and a curved holding-plate, of vertically-movable holding-pins which when in the raisedposition coact with the holding-plate to prevent a coil of metal fromuncoiling.

2. In adevice of the character described the combination with a tableand a curved holding-plate, of vertically-movable holding-pins whoseupper ends lie Hush with the table at the lowered position and extendabove the table at the raised position, for the purpose set forth, across-head by which they are carried, a spring for normally holding saidcross-head at the raised position, and afootpiece whereby saidcross-head may be lowered against the power of the spring.

3. In a device of the character described the combination with a tableand a curved holding-plate, of vertically-movable holding-pins, across-head by which they are carried, a spring for raising thecross-head and holdingpins, means for lowering the cross head againstthe power of the spring and means for locking the cross-head at thelowered position.

4. In a device of the character described the combination with a tableand a curved holding-plate, of vertically-movable holding-pins, across-head by which they are carried, 'a spring for raising thecross-head and holdingpins, means for lowering the cross head againstthe power of the spring, a lockinglever one arm of which is providedwith a handpiece for convenience in operation and the other with a lugadapted to engage the cross-head at the lowered position, and a IOO IIO

spring acting to retain said locking-lever in the engaging position.

5. In a device of lthe'characterdescribed the combination With a tableand curved holding-plate, of vertically-movable holding-pins, guidestherefor secured to the table, a crosshead by which the holding-pins arecarried, a rod 29 by which the cross-head is carried and which isprovided with a footpiece, a guide for said rod, and a spring bearingagainst said guide and the cross-head whereby the latter is normallyheld at the raised position.
